CAUTION: MUTANT MASS is the most complete muscle mass gainer ever developed. The 1,060 calories per serving is based on mixing MUTANT MASS with water. But if you’re looking to go extreme and tip the MUTANT scales, forget the water and mix your serving of MUTANT MASS with 24 oz. of regular (1%) milk instead for a whopping 1,400 calorie mega-shake that contains 76 grams of protein and 212 grams of carbs. With MUTANT MASS you may quickly find your shirts getting much tighter in the shoulder and arm areas. 

Mutant Mass Details

  • Assembled for absurd gains in muscle mass
  • Over 1,000 growth-invoking calories per serving
  • Full experimental dose of protein, clean carbs & critical fats
  • Addictive tasting formula that mixes easily

A New Breed of Mass Gainer

Spawned from countless hours of research and testing on some of the freakiest mass monsters on the planet, MUTANT MASS is a revolutionary, top secret experimental muscle mass gainer that delivers extreme, abnormal mass building results. If you're destroying the iron in the gym to build massive, MUTANT-like proportions of skin stretching muscle and inhuman strength then MUTANT MASS is a must for your mass building arsenal. Every powerful, military strength serving of MUTANT MASS delivers a potent dose of muscle building macronutrients - including exclusive MUTANT PRO® - to shift your body into a state of virtually limitless growth.

Lab Test Shows Shocking Growth

The supplement scientists behind the bleeding-edge MUTANT MASS formula know that building monstrous mass is serious business and you don't have time or money to waste on average, so-called effective mass gainers. So they did their homework and made it their mandate to construct a frighteningly powerful formula, and the results they uncovered were shocking. In an 8-week mass building lab study, a group of researchers tested an experimental formula just like MUTANT MASS and were amazed at its ability to induce significant gains in muscle size and strength! Test subjects using this experimental formula twice a day with their training programs experienced significant gains in lean muscle mass and strength. The researchers even recorded significant increases in muscle size directly on their chest, arms, and legs! The best part is, these guys gained all that mass without even gaining any significant amounts of body fat!

Leave Humanity Behind

Most people think you're crazy, some even call you a MUTANT! But that's ok, you're not anything like them and you never will be. You are focused and driven. You hit the weights like a man possessed day in and day out because you won't settle for being average. You sacrifice daily to be superior and you should demand the same expectations from the supplements you use. You want results - period! The same mega-dense macronutrients delivered in every dose of MUTANT MASS have been documented in research experiments to increase muscle protein synthesis activation when taken soon after your hardcore weight-training session. Increased mass building along with potent calorie-dense macronutrients from MUTANT MASS is the scientific solution to massive gains in muscle size and strength as fast as possible! Don't settle for mainstream formulas that fall short of your high expectations, get on MUTANT MASS today and leave humanity behind!

Mutant Mass - Enhanced for Massive Results

MUTANT MASS is formulated to deliver everything you need to build MUTANT muscle size and iron-smashing strength. One of the true mass building formula innovations of our time, MUTANT MASS exceeds all user expectations for producing results in record time. Just take one look at this super-enhanced experimental formula and you'll see why.

  • 1/10  Horrible results

    By Austin on Sunday, June 14, 2015 12:34 AM

    Effectiveness: 1/10

    (+) Mixes Well,Tastes Great
    (-)  Gave Me An Upset Stomach,Had blood in my stool after trying to take this for a couple weeks (1-2 scoops per serving)

    How did you use it?:Before Exercise,After Exercise,Everyday,Between Meals,Every Morning

    "Did not have a good experience with this product. I tried it for a couple weeks, starting at 2 scoops, and I would have really bad indigestion and painful bowel movements. Went down to one scoop, wasn't much better -- after seeing blood in stool I gave up on this. Since then, have had anxiety before bowel movements probably due to the havoc it caused, and may have developed an intolerance to certain foods which I am still investigating with my doctor. When I eat eggs or certain dairy I feel strange since this whole ordeal but I don't have 100% proof that there is a connection yet."

  • 8.2/10  Mixed feelings

    By Brian Lopez on Saturday, August 31, 2013 08:28 AM

    Effectiveness: 8/10

    (+) Boosts Energy
    (-)  Complicated To Take,Mixes Poorly

    How did you use it?:Before Exercise,After Exercise,Everyday

    "I read good reviews on this high caloric shake. That is why I had decided to give it a try. I did get more energy for my workouts, and I did get a little bit bigger in 2-3 weeks of usage. However, I started to lose my hair (thinning) and it broke me out all over the body. My acne was minimal, but this exacerbated my acne breakouts, obviously with the high amount of carbs and sugars, it makes sense (not to mention that the unnatural ingredients will certainly not boost the healthiness of my internal system. The product is difficult to mix as it is very solid; you must use a blender. I do aknowledges that for some people who have no issues with skin problems or would not affect their hair, that this product might be very suitable, but it was not for me. I will end by saying that the taste is very sugary, and it tastes awful after the last swallow (when finishing the shake off the blender cup). But, if you want to try it, it really isn't expensive to test for yourself."

Suggested Use

Shake or mix 4 scoops of Mutant Mass with 480-960 ml (16-32 fl oz) of water or milk. You can also enjoy 2 or even 3 shakes a day. Our favorite way is to drink one shake first thing in the morning, a second immediately after training; or simply enjoy your shakes whenever you want an extra shot of protein.
